Title: Improvements in or relating to catalysts
IPC: B01J21/14
Filed: 1952-06-16
Abstract: Silica-magnesia catalyst is prepared by reacting or mixing a sodium silicate or a silica hydrogel with a gelatinous complex magnesium oxy-salt, and washing and drying the resulting gel.  A sodium silicate may be used in which 45-85 per cent. of the Na2O has been neutralized to form a silica hydrogel supporting sodium silicate; the molar ratio of silica to soda in the silicate is preferably 0.5:1 to 3.4:1.  Magnesium oxychloride may be prepared by mixing magnesia and a concentrated solution of magnesium chloride with control of the swelling and hydration by addition of water or regulating the temperature; alternatively, powdered magnesia is heated with dry magnesium chloride hexahydrate and the product dissolved in water or magnesium chloride solution.  Oxy-salts may also be prepared from the magnesium salts, e.g. the sulphate, nitrate, iodide, bromide, borate, acetate and formate.  The preferred molar ratio of magnesia to magnesium salt is 0.23:1 to 5:1.  During formation of the silica hydrogel and the gelatinous magnesium oxy-salt, the reactants may stand quietly to form a homogeneous hydrogel or may be agitated to form a slurry of finely-divided particles.  In examples, the mixed gel is washed with hot water and then with magnesium salt solution to remove sodium ions by base exchange; alumina may be introduced into the catalyst by using an aluminium salt in place of the magnesium salt for washing.  The gel may be hot aged overnight at 90 DEG  C. Drying may be effected in a muffle furnace at 450 DEG  C. and activation at 1050 DEG  C.; alternatively, the product may be spray dried.  The final catalyst preferably contains 20-60 per cent. magnesia, and is useful for cracking petroleum oils.

Filed: 1937-06-01
Abstract: 492,464. Filters. BELYAVIN, P. June 1, 1937, No. 15154. [Class 46] [Also in Group XXVIII] An edge filter is built up of elements some of which have annular raised and depressed portions contacting with adjacent elements and can be flexed by flow of liquid in either direction, so that the filter can be cleansed by reverse flow. The filter unit shown in Fig. 4, is built up around a central tube 56 with elongated apertures 57 of alternate plane elements 59 and flexible elements 2 having ridges 4 and depressed margins in contact with the elements 59. The pressure of fluid supplied through an inlet 58 causes the elements 2 to flex so that the fluid can pass through spaces between the ridges 4 and the elements 59 above. The elements 2 will also flex to allow of a reverse cleansing flow. The unit shown in Figs. 1 and 3, has two flexible elements 2 between each pair of plane elements 3. The elements are held in position between end members 9, 10 by tie rods 7 passing through the elements 3 which are spaced by washers 8. The unit is mounted on a block 12 with a bore 14 for the supply of fluid to be filtered and a connection for the discharge of filtrate. A valve 35 is provided by means of which the direction of flow through the element can be reversed for cleansing and a portion of the liquid can be byepassed during cleansing. To increase the capacity of the apparatus a second unit may be arranged against the lower side of the block 12. Fig. 6 shows a unit in which the non-flexible elements have recesses 67 to receive the ridges 4 of adjacent elements and spigots 68 to keep the adjacent elements in correct radial position. In order to eliminate the effect of possible slight unevenness of their surfaces some or all of the elements may be faced with soft material such as fibre, paper, cellulose, cloth or rubber. Specification 463,461 is referred to in the Provisional Specification.

Title: A device for indicating the power-output of engines
IPC: G01L3/24
Filed: 1941-12-01
Abstract: 553,830. Power measuring devices. SQUARE D CO. Dec. 1, 1941, No. 15419. Convention date, Nov. 9, 1940. [Classes 106 (ii) and 106 (iv)] Comprises a speedometer device driven by a shaft, a torque-measuring device incorporated in the shaft, displaceable elements each connected to one of the devices and variable coupling means to couple said devices to a multiplying mechanism working an indicator. A speed device driven from the engine by helical gear 72 and a flexible shaft 76 comprises flyweights 13, 14 carried by toggle levers 15, 16, 17, 18. The levers 15, 17 are pivoted to a collar 19 on the shaft 20. The levers 16, 18 are pivoted to a collar 21 movable against a spring. A further restraint on the collar is provided by a blade spring 24 whose movement is limited by adjustable stops 25 to give a satisfactory speedcharacteristic. The collar 21 is engaged by the forked end 28 of the long arm 26 of a bellcrank lever the other arm 33 of which engages a pin 32 extending from a frame 30 pivoted about the axis 31. Sliding on a frame rod 29 parallel to axis 31, and also on a rod 34 connected to a toothed quadrant 36 is a ratio slider 38 which is moved by the free end of a Bourdon tube 77 moved by pressure fluid according to the torque. The movement transferred to the needle 10 is compounded of torque and speed and is therefore proportional to the power. The torque component is derived in the following manner. The engine crank shaft drives a propeller shaft 44 through a reduction gear comprising a gear 47 keyed to the crank shaft driving a set of planetary gears 49, 50 carried by arms on the propeller shaft. The sun gear 51 is loose on the shaft but has arms 56, 57 linked to pistons 58, 59 located in cylinders 62, 63 filled with pressure fluid supplied by a pipe 65. The two cylinders are connected by a pipe 64 and this pipe is connected by a pipe 70 to the Bourdon tube which also has adjustable reinforcing stops 78 to give the required characteristic. In a modification the frame 30 is moved by the Bourdon tube and the ratio-slider by the speed responsive device. In the Specification as open to inspection under Sect. 91 two additional modifications are described in which the speed responsive device is of the drag type in which an armature is dragged around against spring influence by a rotating magnet and the flux is varied by the movements of the Bourdon tube. This subject-matter does not appear in the Specification as accepted.

Filed: 1961-04-28
Abstract: 942,008. Automatic voltage control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 28, 1961 [May 2, 1960], No. 15467/61. Heading G3R. In a series transistor voltage regulator, the transistor is protected against excessive current by an auxiliary transistor conducts only on overload. The transistor 3 is connected between a source and the load 1, and is normally controlled by a transistor 5 in accordance with the difference between load voltage and a reference Zener diode 4. A fusible link 2 is connected in series with transistor 3, and the voltage drop due to the resistance of the link is applied between base and emitter of the auxiliary transistor 6 so that it conducts when the voltage drop exceeds a given value before the fuse melts. Conduction of transistor 6 maintains the box/emitter voltage of series transistor 3 at a low value and hence the current through it cannot increase much further. Reference has been directed by the Comptroller to Specification 878,990.
Patent GB-1074978-A (GB)
Title: Improvements in or relatin to x-ray diffractometers
IPC: G21K1/04
Filed: 1965-04-12
Abstract: 1,074,978. Diffraction apparatus. SIEMENS A.G. April 12, 1965 [April 15, 1964], No. 15575/65. Heading R5R. A diaphragm for an X-ray diffractometer comprises two plates 1, 2 whose edges 8, 9 define an aperture, the diaphragm being rotatable about an axis disposed centrally between the edges 8, 9 subh that the plane 6 of the diaphragm (passing through the aligned surfaces 16, 17 of the plates) is always parallel to the surface of the specimen at all angles of diffraction. The arrangement of the diaphragm plates 1, 2, which are off-set relative to one another (Fig. 1, not shown), ensures that the edges 8, 9 determine the area of the beam passed, which changes as the diaphragm rotates, such that the area of the crystalline specimen illuminated by the beam from the diaphragm is constant for all angles of diffraction. This enables the decrease in intensity of the diffracted beam which would occur, with increasing diffraction angle 2# (where # is the glancing angle of incidence), when a constant area diaphragm aperture is used, to be compensated by an increasing intensity (proportional to sin 6) when the rotatable diaphragm is used. The diaphragm plates 1, 2 are mounted on a support shaft which carries a gear-wheel 5 at the bottom. This is coupled to a gear-wheel 13, attached to the specimen support, through an auxiliary, resiliently mounted gear 14 causing the diaphragm plane 6 to advance by exactly the same angle as the specimen plane during any rotation of the specimen. An additional feature of the arrangement is that the surfaces 16, 17 of the plates 1, 2 act as an anti-diffusion screen, i.e. even though the edges 8, 9 in fact are sources of scattered radiation, the surfaces 16, 17 prevent any of this from reaching the detector. The diaphragm plate edges may be suitably shaped to provide a rectangular, circular &c. beam and their distance apart is adjustable in setting up the apparatus.

Each of a plurality of inward flow endless gas filter sleeves 29, Fig. 2, pass round a driven roller 30 and round a stationary support tube 31, parallel to and spaced therefrom and having a slot 46 extending across the width of the sleeve through which compressed air is blown to remove dust from the outer face of the sleeve. The edges of each sleeve are held by the pressure difference between in inside and outside in sealing engagement with flange surfaces 38, Fig. 8 and 381, Fig. 3, of vertical brackets 32, 321 secured to opposite end walls 20, 21 of the filter casing and carrying at their upper and lower ends the roller 30 and tube 31. In operation dust-laden air enters the casing through an inlet 24 and clean air from inside each sleeve 29 is discharged into a chamber 26 and compressed air from an external manifold 71 is fed through flexible tubes 67 to one end of each tube 31. Tensioning of each sleeve is effected by a vertical strut 58 pivoted at its lower end to ears 60 of the blow tube 31 and having rollers 61 at its upper and bearing against the drive roller 30 ; the strut being supported by a brace 59 which when released from a pivot 70 allows the blow tube to approach the drive roller for removal of the filter sleeve. A brush or scraper may be positioned near the air jet but on the outside of the sleeve.
